Very very minimal addition to the code with large added functionality.

It poses no risk to anyone not interested in using it.

It's like the new electrical outlets with a usb port in it. It uses up a small bit of space that was not beingbused before, but now you can do so much more. You can plug a fan, a light, a phone directly without an adapter.

It adds the ability to do anything anyother alt-coin claims to do, like zero knowledge proofs, or eth contracts or an even a better version of lightning, without needing anyone who is not interested in these things, to participate.

This means people who like altcoins can start using their hash power and money in securing and spreading bitcoin use instead of going out of ecosystem. Most will stick to the old shitcoins, but DC removes their founding reason for existing : that bircoin can't do certain things.

These examples exist by the way, ethside and zcashSide, on DC.

It moves changes to core up one level, keeping core slow and predictable.

It increases user sovereignty.

It provides real scalability with actionable code ready to go live now, not some idea or thought project that needs years more to develope and launch.

It takes federated and closed source ideas like Liquid, and opens it up to more people. Decentralized Liquid sounds good to me.

It does not give miners more power over the bitcoin network or even over the sidechain.

It does not change the number of bitcoin.

It does not create shitcoins on bitcoin.
